Project info for 3pi Robot

I'm involved in developing the 3pi Robot, which is a small
(3.7") circular robot based on an ATmega168 microcontroller.
Since it has five reflectance sensors, can drive over 1
m/s, and can make precise turns, it's great for line
following, maze solving, etc. You might be interested in
going straight to the User's Guide,
which has lots of pictures and example code.
